Transparent materials sensor needs no reflector

SICK's TranspaTect photoelectric distance sensor achieves the most advanced clear material detection to date without the need for a reflector.

The TranspaTect’s high optical performance and detection accuracy promise better production efficiency, cost-savings, and quick and easy commissioning for packaging and bottling processes such as picking, placing, labelling and printing.

No reflector is needed on the conveyor to return the light beam. Operators no longer have the time-consuming task of mounting the reflector and aligning the sensor to it. The push button teach-in process also facilitates rapid commissioning and set-up.

Instead of a reflector, the metallic surface of a convenient machine component is used a reference surface, opening up extra design freedom for packaging machine builders.

A new AutoAdapt feature automatically compensates for sudden contamination of the lens by dust or product residue, and then re-establishes the original threshold levels when it is cleaned. False readings and line downtime are therefore minimised and intervals between cleanings can be extended.

The SICK TranspaTect photoelectric sensor is based on a high performance PinPoint LED which emits a tight, highly visible spot for easy visual reference. The detecting range for transparent objects is 0 – 400mm and the background reference range is 150 – 700mm.

IP66/67 rated, the SICK TranspaTect has ECOLAB certification relating to its resistance to aggressive cleaning regimes, disinfectants and chemicals. The compact (15.6mm x 48.5mm x 42mm) rugged die-cast zinc housing is available with an optional PTFE chemical resistant coating.
